FileSync

Synchronization utility that allows you to maintain the current status of files or directories on your computers, laptops or servers. Simply specify the source and destination directories and the program will generate a list of relevant files that differ, along with an indication of where to conveniently copy the more current file from.

In addition to comparing by file size and time of creation, FileSync also offers a binary comparison option, which is useful, for example, for verifying the integrity of a burned CD.
